Tired of doing db.session.add and db.session.commit to save your records? Have no fear, save is here. Note: This is for use with Flask-SQLAlchemy

core.py

from .user import User

def init_db(db):
    """Add a save() function to db.Model"""
    def save(model):
        db.session.add(model)
        db.session.commit()

    db.Model.save = save


db = SQLAlchemy()
init_db(db)

u = User(email='foo@foo.com', password='test!1234#')
u.save()

user.py

import bcrypt
from .core import db

class User(db.Model):
    __tablename__ = 'users'

    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(255), unique=True, nullable=False)
    password = db.Column(db.Text, nullable=False)

    def __init__(self, email, password):
        self.email = email
        self.password = bcrypt.hashpw(password, bcrypt.gensalt(12))

    def __repr__(self):
        return '<User %s>' % self.email
